Corequity Annual Report – 2017

2017 was an unusually good year for our monthly screens for Undervalued and Overvalued stocks.  Our Undervalued Screens outperformed the S&P 500 by 13.6% while the Overvalued underperformed by 17.6% relative*.

The resulting spread of 31.1% between the two Screens compares to a spread  of +7.9% per annum since inception in 2004.  Putting in another way, 2017 was 4 times better than normal.

An analysis of the Sector drivers for the performance of Undervalued and Overvalued is summarized in the following tables which show the sum of the Sectors’s equities’ Relative Strength throughout the year:

Screen RS 1

Screen RS ov

The sum of Relative Strength by Sector indicates which Sectors contributed most to the performance.   In both screens one Sector accounted for the majority of the net performance.

In the Undervalued Screens, it was Technology which contributed 61% of the net performance, followed by Industrial (25%), Consumer Cyclical (12%) and Basic Material (7%).

Accounting for the Overvalued’s underperformance, Energy was the major contributor (62%) followed by Telecommunications (11%), Financial (10%) and Consumer Cyclical (9%).


Looking ahead, the following are summaries of our current screens by Sector. VR is the average Valuation Return or Risk, and E/M is the Estimate divided by the normalized earnings (MPEPS).

*  The Screened companies are from our universe of over 400 equities.  They are selected on the basis being in two of  the best, and worst, quartiles including Valuation Return/Risk  (VR). The Undervalued had an average of 22 equities while the Overvalued averaged 28.


Corequity Results since Inception[1]

Corequity has been screening its equity universe since 2004. The monthly results shown below cover 13 years, from September 2004-2017 The Undervalued Screen has achieved an average annualized gain over the S&P 500 of 5.20% while the Overvalued underperformed by 2.76% for a spread of 7.95% pa.

13 yrs relative to univ

While this may not seem like much to some, it is enormous. This chart shows what the actual gains would have been on an investment of $100 over the period.  The Undervalued Screens produce a return that is over 5.5 times that of the Overvalued.

Short Term Results (16 months)

The performance of the screens have been particularly consistent since June 2016 as the graph below shows. The Undervalued have outperformed our Universe by 31% while the Overvalued underperformed by 19% for a spread of over 50% in 16 months.

Analysis of Short Term Results: Undervalued

The following tables on sectors and stocks show which were the largest contributors to these results.  The tables show the sum of the Relative Strength (to the S&P 500).


Here we can see that the major contributors to the superior performance of the Undervalued Screen were Technology, Industrial and Consumer Cyclical.

The top and bottom Undervalued stocks which contributed the most (and least) are shown here: ANALYS UV

Analysis of Short Term Results: Overvalued


The Sectors which contributed the most to the underperformance of the Overvalued were Energy, Financial and Basic Materials.  The individual companies in the top and bottom 10 are as follows:


These attribution tables do not answer the question of why these results have been so consistent in the last 16 months.

A simple explanation would be value vs growth but this doesn’t hold up as the underlying principal of Corequity analysis is to put a price on growth specific to each company.  This is further supported by the recent relative performance of the ETFs SPYG and SPYV, being the Spider ETFs for S&P 500 Growth and Value stocks.


This bears no resemblance to the UV/OV screen graph for the same period especially  if the same scale is used.
